GAS

Application 'filed October 3, 1921.

To all whom it may concern Be it known that l., HERMAN E. Lonen, acitizen ot the United States, and a resident of Jersey City, in thecounty of Hudson and State ot New Jersey, have invented new and usefulimprovements in Gas Heaters, of which the following is a full, clear,and exact description.

rlhis invention relates to improvement-s in gas heaters. i

The usual type of' gas heater, when in use, gives rise to anobjectionable smell due to the incomplete combustion ofthe gas. rihis isvery unsatisfactory when the heater is used in apartments or nooms, andthe gases escaping to cause this smell are injurious to the health ofthe occupa-nts.

The object et this invention is to provide an economical gas heaterprovided with means ior causing more complete combusu tion than usual soas to eliminate smells and which give great eiliciency in the heatingpower t'or the amount or" gas consumed.

A further object is the provision of mea-ns for retaining the heat sothat after the gas has been discontinued the heater will continus toradiate heat.

rl`his object is accomplished by mounting in the mantle located shovethe burner, av

flame spreader that delays the progress of the gases so as to cause goedcombustion, and constructing the mantle and flame spreader of a materialthat retains heat.

These and other objects ot the invention will be more clearly understoodfrom the following detailed description and accom-- panying drawings.

Figure 1 is a. vertical section through the heater;

Figure 2 is a section on the line 2 2 Figure 1; f

Figure 3 is a section along the line Ps-3., Figure 1;

Figure l shows in detail the air inlet.

Referring to the above-mentioned drawings, a base 10, which is ofconsiderable weight, is provided to support the various parts orn theheater. Mounted on this base is a gas inlet 11 to which gas is suppliedby means or" a gas supply pipe 12. rEhe upper part of the gas inlet 11is threaded and has a coupling 13 making a threaded engagementtherewith. Entering the coupling is an air inlet 1e. A set screw 15 ismounted in the wall ot the air inlet and serves as a Serial No. 565,005.

means tor controlling the amount of air that enters. Connected to the'upper end oi the coupling 13 is a tube 16 which car ries a number ofsupporting arms 17. rlhe upper ends oi these supporting arms extendradially outward and have an annular plate 18 integral therewith. Twoconcentric flanges 19 and 20 extend upward from the annular plate 18. Aperforated casing 21 is held in position upon the annular plate 18 bymeans of the flange 19. A two-piece tubular casing made up ot sections22 and 23 is held in position on the annular plate l'by means ot theflange 2O and the screws 24 which project through the supporting arms17. A cover 25 4having its center port-ion cut away is mounted on thecasing 21 and is held" in position by means of the bolts 26. Aperforated lid 27 is provided to close the central opening in the cover25. An ornamental top 28 provided with a pin 29 extending verticallydownward is located above the lid 27, the pin 29 engaging in an openingin the center of the perforated lid. rl`he two-piece tubular casing ismade up ot sections 22 and 23'. The annular sections. which are otgreater diameter at the top than at the bottom have flanges about theirlower ends that project radially inward. rihe upper section 23 has ashoulder 30 cut around the-outside ot this lower end. This shoulder 30rest-s uponthe upper edge ot the lower section and serves as a means forsupporting the upper section upon the lower section. Screws 31 extendthrough the wall ot the lower section into the threaded openingsprovided in section 23 and serve to hold the two together. The sectionsof this tubular casing are preferably made ot cast iron but might bemade from other materials.

The 'flame spreader consists ot 'an annular plate 32 having integraltherewith an arm 33 that supports the spacing hub 34, upon the ends ofwhich two dish-shaped plates 35 and 36 are mounted. rllhese dish-shapedplates are mounted so that they tace inward. Radial grooves 37 are cutin the edge of the lower tace of the plate 35. r1`he plates 35 and 36are greater in dia-meter than the opening in the center ot the annularplate 32 but smaller in diameter than the external diameter of theannular plate. Their diameter is also less than the diameter of thesections of the mantle. I:Phe flame 'spreader is mounted on the flangeof section 23 by means of the plate 32. This flame spreader ispreferably constructed of east iron so that it will retain heat.

When the heater is in use the flame passes up .into the mantle andstrikes the lower face of the plate 36 and is forced to the side,passing around the edges of the mantle. lt then passes up through theopening in the annular plate 82 and comes into contact with the lowerface of the plate 35. The lower plate is shaped for spreading the flameso that it travels toward its edges. `lVhen the flame and gases come incontact with the lower' face of the plate they escape partially throughthe grooves 37 and pass around the edges of the plate 35. rl1 he shapeof the plate 35 causes a whirling motion ot' the gases and delays themsufliciently to cause complete combustion. rllhe heater and the mantlebeing constructed of cast iron retain a considerable amount of heat andonce they have been heated the supply oit' gas may be cut down and theheater' continues to radiate a considerable amount of heat. lThe heatercasing 2l is perforated so as to allow the heat to escape freely. e.perforate lid 27 is provided in the top of the heater so that theornamental cover maybe removed and the heater used for heating water orother like purposes.

l would state in conclusion that while the illustrated exampleconstitutes a practical embodiment of my invention ll do not limitmyself strictly to the exact details herein illustrated since manifestlythe same can be considerably varied without depart ing from the spiritof the invention as defined in the appended claims.

Claims:

l. ln combination with a heater a flame spreader of the class described,comprising an annular plate supported in the heater, a spacing hubextending to each side of the annular plate and supported thereby, andtwo dish-shaped plates, one mounted on each end ot the spacing hub andboth facing inward, the upper plate having grooves cut in the edge ofits lower face extending radi ally outward.

2. ln combination with a heater, a flame spreader of the classdescribed, comprising an annular plate supported in the heater, aspacing hub extending on each side ofthe annular plate and supportedthereby, and two dish-shaped plates of greater diameter than the innerdiameter of the annular plate, one mounted on each end of the spacinghub and facing inward, the upper plate having grooves cut in the outeredge of its lower face, said grooves extending radially outward.
